FLOOR-DRESSING MACHINE.

Specification of Letters Patent.

Patented April 3, 1906.

Application filed Aug 3;, 3355 Serial No. 276.65 2

To all whom it may concern:

Be it known that we, Fnnn R. BUMPUS and JOHN KYLE, citizens of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented new and useful Im rcvements in Floor- Dressing Machines, which the following is a s ecification.

his invention relates to machines for levcling and smoothing floors and our improvements consist in a frame having rear su porting-wheels, a truck mounted on whee s, means for adjustably connecting the forward part of the frame with the truck, a floordressing roller journalcd in the'front end of the frame, and means for simultaneousl operating the floor-dressin roller and mac line, as hereinafter describe Onr improvements further consist in certain combinations and arrangement of parts, ail of which are hereinafter fully described and s ecifically claimed.

Re erring to the drawings, Fi no 1 re resents a side elevation of the mac e as w en ready for o oration. Fig. 2 is a view of the front end tlereof. Fig. 3 shows a modification of the means emplo ed for o crating the dressing or smoothing evice. Eig. 4 IS an enlarged sectional view of the floor-dressing roller with means for holding sandpaper or emery-cloth thereon. Figs. 5 and 6 represent metallic lates having roughened or cutting surfaces or action on the projecting surfaces of the floor. Fi 7 is a perspective view of an auxiliary end roller.

On the drawings the numeral 1 designates the frame of the machine, which somewhat resembles that of a bicycle or velocipede. The sides 2 3 of this frame are similar in outline, resemblin somewhat the letter A, with the lower en s thereof connected by do licate horizontal side bars 4, the rear ends 0 which are connected by journal-boxes 5 with an axle 6, having supporting-wheel 7 at each end thereof. The forward ends of the side frames are each provided with suitable journal-bearings for receiving the ends of a shaft 8, on which is secured the floor-dressing roller 9, the periphery of which is provided with a longitudinal groove 10 to receive a lockingwedge 11, which is preferably formed of spring-steel, so as to secureiy hold the opposite ends of the emery-cloth or sandpaper with which the roller is wrapped when the smoothing or finishing touches are given the floor. Howver, before the application of sandpaper or emery-cioth to the aforesaid roller a series of steel plates 12, file-cut or rasped, are bolted or otherwise secured around the peri hery of the roller, so as to out down all pro ections and reduce the floorsurface to a perfect level, which being accomlished the said steel plates 12 are removed from the roller and the sandpaper or emeryclotli substituted therefor, as above mentioned.

In the rear of the roller 9 the side frames are connected with a transverse frame or truck 13, having supporting end wheeis 14, the truck being provided with adjusting screws 15, whereby the roller is relieved of superfluous weight and a proper level thereof maintained. A scoop or dust-catcher 16 is connected with the truck 13 on the forward part of the frame to receive the dirt or dust resulting from the action of the roller 9 dur' ing the wnrkin r of the machine. The upper part of the si e frames are each provided with a iournal-bearing for receiving the journals of a drivin -shaft 17, havin end cranks 18 provided wit 1 handles 19,wit 'n comfortable reach of which the rear of the machine is provided with an operators seat, as shown at 20 in Fi 1. The horizontal bar 21 of the A-shape side frames are each provided with journal-bearings to receive the end journals of a transverse shaft 22, carrying a sprocketwheel 23 and pinion 24, the former adapted 7 to be driven by a chain 25 from a pinion 26 on the driving-shaft 1?, the pinion 24 serving to transmit motion throu h a chain 26 to a sprocket-wheel 27', secured on the rear axle 6 of the machine.

The working roller 9 receives motion from the driving-shaft 17 through a bevel-wheel 28, mounted on said shaft, a pinion 29 en,- gaged therewith and keyed or otherwise secured to the upper art of a rod 30, which is journaled in suitabfd bearings forming art of or connected with the forwardl inchned member 31 of one of the A-shaped side frames of the machine, the lower part of the rod being provided with a second pinion 32 to engage a hevei-wheei 33 on the adjacent end of the workin roller.

In lieu o the roller-driving mechanism described the driving-shaft may be provided with a cog-wheel 34, as shown in Fig. 3, the said cog whee! being ada ted to on age through an idler 35 a pinion 336, the she t 37 of winch is provided with s sprocket-wheel 23. from which power is transmitted through a chain 39 to sprocket-pinion 39, connected with the shaft of the working roller 9.

The forward part of the machine is provided with a guard-plate or bar 40, which is intended to contact with the base-board of the room before the working parts of the m achine can injure the walls thereof.

The traction-wheels of the machine are provided with rubber tires to insure frictional contact with the floor, as Well as to prevent scratching or marring the same.

To provide for finishin up to the baseboard, auxiliary end rollers? are adapted to be temporarily secured on the projecting ends of the roller-shaft 8, as shown in dotted lines at b in Fig. 2, rubber or other suitable fenders a being secured to the ends of the aforesaid shaft to prevent same from marring the wall or base-board thereof.

Having described the invention, what is claimed, and desired to be secured by Letters Patent, is-

1. In a floor-dressing machine, the combination with a frame having supportingwheels at the rear end thereof, and a supporting-truck connected with the forward part of same, a floor-dressing roller journaled in the front end of the frame, means connected with the truck for changing the elevation of the forward part of the frame and means for simultaneousl) o eratin the dressing -roller and propellin tie mac 'ne.

2. The com ination in a floor-dressing machine, of a frame havin sup ortingwheels at the rear thereof, a true an means wherebg' the forward part of the frame is adjust a 1y connected therewith, a shaft journaled in the frame in advance of the truck having mounted thereon dressing rollers, one of which being located between the sides of the frame and the others upon each end outside of the frame, a drivingshaft and separate means for transmittin motion from said shaft to propel the mac inc and operate the floor-dressing rollers thereof, as set forth.

In testimony whereof we have hereunto set our hands this 26th day of August, A. D. 1905.
